Hard Drive Installation and Replacement
General Information About Hard Drive Failure
Appendix C 143
There are other ways to recognize that a hard drive has failed:
• The amber LED lights up on the front of supported StorageWorks
disk enclosures, if failed drives are inside. (Other problems such as
fan failure, redundant power supply failure, or over-temperature
conditions, will also cause this LED to light up.)
• Event Monitoring Services (EMS) will cause an alert message to be
sent when physical or logical drive failure occurs. See “Event
Monitoring Service (EMS)” on page 113, for details.
On Off Off Do not remove the disk drive. Removing a drive
during this process may cause data loss.
The disk drive is being accessed, but (1) it is not
configured as part of an array, or (2) it is a
replacement drive and rebuild has not yet
started.
On Flashing Flashing Do not remove the disk drive. Removing a drive
during this process can cause data loss in
non-fault-tolerant configurations.
Either (1) the drive is part of an array being
selected by saconfig, or (2) sautil is
upgrading the drive firmware.
Off Off On OK to replace the disk drive online. The drive
has failed and has been placed offline.
Off Off Off OK to replace the disk drive online if the array
is configured for fault tolerance and all other
drives in the array are online. Either (1) the
drive is not configured as part of an array; (2)
the drive is configured as part of an array, but a
powered-up controller is not accessing the
drive; or (3) the drive is configured as an online
spare.
